ICD-10 Code D70.2 – Other drug-induced agranulocytosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D70.2 – Other drug-induced agranulocytosis
What it is
D70.2 identifies agranulocytosis caused by a drug or medication. It means the patient has a severe loss of granulocytes, usually recognized as a serious adverse drug reaction.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include sudden infection, sore throat, fever, or mouth ulcers with a provider note linking the condition to a drug exposure.
When to use this code
Use this code when the record clearly states agranulocytosis is drug-induced and the drug cause is not otherwise specified by a more exact code. You should rely on provider documentation, especially when the medication is named. If the note only says neutropenia or low white blood cells, check documentation.
Do not use for
Do not use D70.2 for congenital, cyclic, or other non-drug causes of agranulocytosis. It is also incorrect when the chart documents only leukopenia, neutropenia, or an adverse effect without agranulocytosis.
Coding tip
Confirm the medication cause and the word “agranulocytosis” in the provider note before assigning D70.2.
